TUB-SECURING- SUPPORT.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed October 26, 1916. Serial No. 127,854.

To all whom t vmay concern.'

Be it known that I, THOMAS S. MoR'roN, a citizen of the United States, residing at Tuxedo Park, in the county of Orange and State of New York, have invented new and useful Improvements in Tub-Securing Sup ports, of which the following is a specification.

This invention relates to improvementsin means for securing portable cylindrical tubs and the like firmly with relation to the foundation upon which they are placed.

The principal object of the invention is to provide means applicable to small tubs or tanks, such, for instance, as are used in connection with domestic ice cream freezers, Y

so that the same may not move while being operated, but are held firmly with relation to the floor or platform upon which they may be placed until it is desired to release the same.

A further object is to provide such clamping means in the nature of attachments which are applicable to a relatively wide range of tubs, varying both as to height and diameter.

These and other like objects are attained by the novel design, construction, and combination of parts hereafter described and shown in the accompanying drawings, forming a part of this specication, and in which:-

Figure 1 is a perspective view showing in broken lines a common form of tub, and in full lines an embodiment of the invention applied thereto.

Fig. 2 is a partial transverse sectional view of the same.

Fig. 3 is a fragmental plan view, drawn to an enlarged scale and showing the arrangement of teeth used in the clamp tightening device.

Fig. 4 is a transverse sectional view taken on line 4 4 of Fig. 2.

Fig. 5 is a fragmental transverse sectional view taken on line 5 5 of Fig. 1.

Fig. 6 is a sectional view taken on line 6 6 of Fig. 2.

Fig. 7 is a fragmental plan view indicating the clamp shifting device, and

Fig. S is a side view of the same.

One of the great difficulties entertained in making ice cream and the like in the home is the inability to readily maintain the ice tub in which the freezer operates in a fixed substantial position, and it is for this specific purpose that this apparatus was designed.

Referring to Fig. 1, the ordinary cylindrical tub or tank 10 is indicated by broken lines showing the disposition of the freezerI 11, together with its shaft 12 and operating crank handle 13. The tub as indicated is shown to stand upon a platform 15, from which rises a rigid standard 16 which may be fastened to the wall if desired, and secured to the face of the standard is a vertical bar 17, provided near its upper end, with a slot 18 passing through the bifurcated upper end which contains a slidable element 19, adapted to be secured at any desired height by the wing bolt 21 passing through the slot.

The slide 19 is formed with an angular projection 24 at its upper end, the projection terminating in a downturned hook 23 adapted to engage within the interior of the tub, the extending element 24 resting upon the top of the tank.

At the lower end of the bar 17 is a foot 26 in which is secured a` spur 27 engageable with the bottom of the tank, and by means of which it is prevented from movement under normal circumstances, the tub hook 23 passing under the tub wall.

In order to hold the bottom of the tub absolutely secure, there are engaged with the fixed bar 17 a pair of metallic bands 30 and 31, the former of which is adapted to embrace a greater portion of the tub near its bottom, and has inserted at regular intervals near its extreme end, a plurality of rigid pins 33 engageable by the teeth of the gear 35 rotatably mounted on a bracket 36 secured to the band 31, thel gear 35 being mounted upon a pin 38 by `means of which the lever 40 is fulcrumed to the bracket 36.

A pawl having double acting arms 41 and 42 is pivoted at 43 to such height that the ends of the pawl may engage with the gear teeth as the lever 40 is oscillated back and forth by means of the handle 45.

Thus the gear 35 may be rotated and by reason of its engagement with the pins 33 the band can be rigidly tightened around the tub holding it securely in position.

When it is desired to release the tub, the knob 46 is operated, the same being secured on the bell-crank lever 47, pivoted at 48, upon the lever 40 and held normally downward in operative position by the spring 49,

the lower end of which is engaged with the pin 50 set in the lever l0; at the other end 3iof the bell-crank lever l?, is a connecting link 5l arranged to raise the pawl ll as the knob lr6 is operated, allowing the opposite end l2 oit the pawl to become operatively engaged with the teeth of the gear, a pin 55 limiting the action of the bell-crank lever.

From the foregoing, it will be obvious that an elfeetive alriparatus for securing such articles as tubs has been disclosed and that the same may readily be operated without previous experience, the operation consisting merely in inserting the tank or tub in position, adjusting the hook 23 to the height oli' the tub, and clamping it lirmly down, whereupon operating the lever -lO causes the bands 3l) and 3l to rigidly engage and positively hold the bottom oit the tub in position.

Having thus described my invention, what. l claim as new, and desire to secure by Letters Patent, is:-

l. In a support for securing tubs, the combination with a platform, an upright standard rigidly engaged therewith and means lor securing said standard to a vertical support, ot a hook slidable in said standard, said hook being adapted to engage with the upper edge of a tub, means for securing said hook in an adjusted position, means at the bottom ot' said standard engageable with the lower edge oit the tub, means tor engaging the tub ciriaimferentiaily near its bottom with said platform, and means vtor tightening or loosening said engaging means.

ln a support for securing tubs, the coinbination with a platform and a standard rising therefrom, of means for engaging the top ol a tub to said staiidari'l, a pair o'll straps attached at one end to said standard, said straps encircling' the tub at the bottom, pins secured upon one ot said straps, a gear operative-ly engaging with said pins, a .lever having pawls engageable with the teeth ol said gear, and means combined with said lever whereby7 said gear may be turned in either direction thereby tightening or loosening said straps with relation to the tnb.

ln a support for securing tubs, the conibination with a plattform, a standard rigidly a l'lixed near one edge of said platt'orm, means combined with the upper end oli1 said standard adapted to adjustably engage the upper edge ol said tub, means at the bottom olf said standard engageable with the lower edge oli said tub, a flexible ba nd attached at one end to said standard and partially encircling the tub, a second flexible band attached upon the opposite side ot said standard, a` bracket combined therewith, said bracket slidably receiving the tree end ot' the lirst mentioned band, teeth set in the lirst mentioned band, a gear pivotally supported in said bracket engaging with said teeth, a lever fnlcrumed on said bracket, a double ended pawl carried by said lever, said pawl being engageable with the teeth ot' said gear and adapted to convey rotary motion upon oscillating said lever, and means carried by said lever for causing either end ol said pawl to engage with said gear, whereby said bands may be retracted or expanded relative to the body1 of the tub.

In testimony whereof I have signed my name to this specification.

THOMAS S. MORTON.
